WS_E_ENDPOINT_ACTION_NOT_SUPPORTED
WS_E_ENDPOINT_ACTION_NOT_SUPPORTED is a Windows Web Services API HRESULT. It means that the service endpoint rejected the requested message action or operation because it is not implemented, published, or permitted by that endpoint.
Diagnostic discriminator: Hold the endpoint and transport constant and compare the failing action with an operation advertised by the same service contract. If the known action succeeds, the endpoint is reachable and the failure is at the message-contract layer. Preserve the exact action URI, binding and server contract version before changing routing or transport settings.
What to check for WS_E_ENDPOINT_ACTION_NOT_SUPPORTED
- Compare the requested action, SOAP action or operation name with the active service contract.
- Check client and server versions, routing rules and endpoint bindings after deployment changes.
- Do not reinterpret an unsupported action as a transport failure.
